- Apply a 4.0 mm (0.157 in) patch of adhesive GM P/N 12346141 (Canadian P/N 10953433) or equivalent, to the cylinder head side of the lower intake manifold gasket at each end.
- Install the lower intake manifold gasket onto the cylinder head.
- Apply a 5 mm (0.197 in) bead of adhesive GM P/N 12346141 (Canadian P/N 10953433) or equivalent, to the front top of the engine block.
- Extend the adhesive bead 13 mm (0.50 in) onto each lower intake manifold gasket.
- Apply a 5 mm (0.197 in) bead of adhesive GM P/N 12346141 (Canadian P/N 10953433) or equivalent, to the rear top of the engine block.
- Extend the adhesive bead 13 mm (0.50 in) onto each lower intake manifold gasket.
- Install the lower intake manifold onto the engine block.
- If reusing the fasteners, apply threadlock GM P/N 12345382 (Canadian P/N 10953489) or equivalent, to the threads of the lower intake manifold bolts.
- Install the lower intake manifold bolts.
- Tighten the lower intake manifold bolts.
- Connect the evaporative emission (EVAP) canister solenoid valve harness.
- Install a NEW oil pump drive shaft gasket onto the oil pump drive shaft.
- Install the oil pump drive shaft and oil pump drive shaft clamp.
- Install the oil pump drive shaft bolt. Tighten the oil pump drive shaft clamp bolt to 25 N·m (18 lb ft).
- If required, install the ignition coil bracket and bolts. Tighten the ignition coil bracket bolts to 12 N·m (106 lb in).
- Install the ignition coil and ignition coil bolts and tighten to 12 N·m (106 lb in).
Caution: Apply the proper amount of the sealant when assembling this component. Excessive use of the sealant can prohibit the component from sealing properly. A component that is not sealed properly can leak leading to extensive engine damage.
Note: The lower intake manifold gasket must be installed while the adhesive is still wet to the touch.
Use the gasket locator pins in order to properly seat the lower intake manifold gasket on the cylinder head.
Note: The lower intake manifold must be installed and the fasteners tightened while the adhesive is still wet to the touch.
Caution: Refer to Fastener Caution in the Preface section.
Caution: Proper lower intake manifold fastener tightening sequence and torque is critical. Always follow the tightening sequence, and torque the intake manifold bolts using the 3 step method. Failing to do so may distort the crankshaft bearing bore alignment and cause damage to the crankshaft bearings.
| 10.1. | Tighten the bolts on the first pass in sequence (1-8) to 3 N·m (27 lb in). |
| 10.2. | Tighten the bolts on the second pass in sequence (1-8) to 12 N·m (106 lb in). |
| 10.3. | Tighten the bolts on the final pass in sequence (1-8) to 15 N·m (11 lb ft). |
| 11.1. | Push the elbow inward until the quick connect snaps into place. |
| 11.2. | Pull the elbow outward in order to ensure proper connection. |
